The first option is the right answer
Answer:
Option (1)
Step-by-step explanation:
Surface area of a cylindrical vessel is given by the expression,
Surface area = ![2\pi r^{2}+2\pi rh](https://tex.z-dn.net/?f=2%5Cpi%20r%5E%7B2%7D%2B2%5Cpi%20rh)
= ![2\pi r(r+h)](https://tex.z-dn.net/?f=2%5Cpi%20r%28r%2Bh%29)
Here, r = Radius of the vessel
h = Length of the vessel
By substituting the values of 'h' and surface area in the expression,
2πr(12 + h) = 540
Therefore, Option (1) will be the correct option.
Answer:
C and G
Step-by-step explanation:
Given
(x - 2)² = - 3x + 6 ← expand left side using FOIL
x² - 4x + 4 = - 3x + 6 ( subtract - 3x + 6 from both sides )
x² - x - 2 = 0 ← in standard form
(x - 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2 → G
x + 1 = 0 ⇒ x = - 1 → C
You can multiply .72 by 350 because 72% is actually a decimal of .72. In these types of question of means to multiply so the answer would be 252
Answer:
Y=t+5
Step-by-step explanation:
Bob starts running...(1)
Bill starts running 5 seconds later...(2)
From (1) and (2) we know that Bob had been running for 5 seconds when Bill started running.
The expression we are looking for is
Y=t+5
Y is the number of seconds Bob has been running
t is the number of seconds Bill has been running
